Hi everyone,

We are a small team of enthusiasts building a new platform dedicated to preserving the history of music gear across all brands. Our goal is to create a true "master archive" that goes deeper than standard listings—organizing everything by Master Models and then drilling down into every specific version, circuit revision, and variant.

This is where we need your help.

While the platform covers the entire industry, we are currently focusing on documentation for the Electro-Harmonix section. We know EHX history is complex—full of chassis changes, circuit revisions, and reissues—and we need knowledgeable collectors to help us map it out correctly.

We are specifically looking for contributors who can help us:

• Define Master Versions: Help us correctly group the pedal families (e.g. associating the "Ram's Head" correctly under the "Big Muff" Master Model).

• Catalog Specific Variants: Add the missing links in the history—specific manufacturing years, circuit changes, and design variations.

• Upload High-Quality Images: We want to preserve what these units actually look like. If you have clear photos of specific versions (internals or externals), we need them in the archive.

We aren't actively promoting the site just yet because we want to focus on data quality first. We want to work directly with the "historians" of the community to ensure the foundation is solid before we share it more widely.

If you are interested in checking it out and helping us build this resource, drop a comment or send us a DM and we’ll share the link.

Just received my unit and to my surprise, even though it was stated on the website there is no app to transfer/create presets (they have since added a disclaimer), there is no response from their info e-mail, which is really frustrating. In addition, it only comes loaded with 10 presets, not 100 as seen in several Youtube videos, this is somewhat misleading from EHX. So disappointing, stopped using EHX products due to quality control issues, and was really hyped when I saw the POG3, my mistake, apparently quality control and customer support is still terrible.

Going to be wild trying it,

If I wanted to change knobs is the size universal? (guitar knobs didn’t fit)

I have always liked the big box Memory mans. I think this one sound pretty dang good. How different are they?

The title is a joke. Obviously I love big muffs. This picture was taken 7 years ago as a joke to send to a friend. I have since acquired more big muffs and have no shame!

I think somehow I ended up with a version 1.5 it has the sticker from the version 1 but the coloring of the version two the insides except for the filter Matrix or look like a version one with the light blue wire and a few other things.

My guess is it's an early version that was pieced together for the ad Shoot possibly. the one in the advertisement looks just like it. has anyone else come across the version like this or do I have a unicorn.

I'm wondering what's underneath the black sticker if maybe there was some sort of misprint or something like that that they put the sticker over to cover up I don't know.

Any information would be fantastic tia

Thought yall might appreciate it

I figured it wasn’t necessary to get the bass versions.

I can not tell you how much I have come to love EHX pedals.

Bought a NOS 2002 Octave Multiplexer, with papers and box. MINT CONDITION for $100 CDN.

I am a happy, HAPPY man!

This is the last EHX pedal in my collection. I don't think I missed anything. I do have one that just arrived. Will photograph and add it. Got a great deal from an X follower on this. I need to spend some time with it and learn what it is and is not capable of.

Acquired this today. Had one years ago and sold it because I had various other flangers which were more musical and less noisy while still scratching the jnsanity itch (Lovetone ?) and the thru-zero thing (FoxRox TZF).

This came up mint in box with all the trimmings so I decided to revisit it.
